Transponder Chips

If your car is made in the last 20 years, it is likely that it has a transponder inside of it. This is the little plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to your car.

The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal is then received by a specific antenna attached to the ignition barrel. The computer system in the vehicle can then verify that the key's transponder chip is the right one for your car.

This prevents the vehicle from being started by hot-wiring, or by altering the key. The chip in the car key ensures that the owner is the one who owns the vehicle. This can reduce car theft.

Transponder keys look like regular keys made of metal but have a plastic cap. The chip is housed inside the plastic portion of the key, and there are different types of cuts on the keys: a cut, a laser Cut And Program Car Keys (also known as a sidewinder key) or Ford Tibbe key.

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal will then get absorbed by the chip and cause it to send a signal back to the car. If the car's computer detects this signal as the right one, it will shut down the vehicle immobilizer and allow the engine to begin.

If the car isn't able to recognize the transponder as a valid signal, it won't start the engine and notify you via flashing lights and an alarm. This is designed to discourage people from trying to tamper with the vehicle, however it's not a 100% security measure. A skilled and determined thief could still be able to escape this security system by employing a device designed to intercept the signal.

As you can see there are quite few advantages to getting transponder keys. All car owners should take this into consideration when they want to safeguard their investment and reduce the risk of theft.

Key Fobs

Key fobs today can offer more than locking and unlock doors. They can also turn on the car remotely, make chirping noises to help locate the car or switch on the heated steering wheel. These additional features can make it difficult for you to locate your car keys.

Key fobs make use of radio frequencies to communicate with one another and with the car. The frequencies are transmitted by a small antenna within the middle of the key. The communication is encrypted, which helps to keep others from stealing and retransmitting the signal.

You can program a keyfob in various ways based on the model and brand of your vehicle. Certain cars let you do this yourself. However, most newer models require you to visit a professional locksmith or dealer for them program a replacement key fob, or an alternative one.

When you press the button on a key fob, the microchip sends an indication to the receiver in the car with which it is linked. The receiver compared this information to the 'allowed' signals stored on the fob and either locks or opens the door. If the information isn't in line an chirping sound is heard and the car isn't able to function.

Once the car is paired with a specific fob, it can only receive signals from the device. Other fobs won't work with the car, despite the fact that they appear similar. This is to safeguard the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control over the vehicle.

The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements that are supplied by the manufacturer. It is because the only place with the knowledge to create a replacement fob is in the service department of a dealer. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems can be programmed by customers without the need of dealers.
